Ball Diamond / Infield Mix

Ball diamond mix is a processed material consisting of sand, silt and clay. It is generally used to create or restore infields, pitching mounds, softball and baseball fields. Ball diamond mix provides a field with good drainage, stability, wear resistance and firm traction. The Stone Store supplies ball diamond infield mix to schools, parks and ball fields in the Maryland, DC and Northern Virginia areas.

Fill Materials

Fill material usually consists of dirt, (subsoil) or sand, clay or recycled stone. It is generally used to fill holes or depressions in the ground or to create mounds to artificially change the grade or elevation of land. At The Stone Store we carry several types of fill material such as: soil fill, select fill, structural fill, sandy clean fill, common borrow fill, screened sand, RC-6 recycled crusher run, core trench clay and clay fill.

Fill Dirt is usually subsoil (soil from beneath the top soil) and underlying soil parent material which has little soil organic matter or biological activity. Fill dirt is taken from a location where soil is being removed as a part of leveling an area for construction; it may also contain sand, rocks, and stones, as well as earth.

Fill dirt (or soil fill) should be as free of organic matter as possible since organic matter will decompose creating pockets of empty space within the fill which could result in settling. Settling of the soil fill can and will possibly result in damage to any structures built on the fill.

A common use of fill dirt is in highway maintenance to build up the shoulders of highways so that the ground on either side of the pavement is at the same level as the pavement itself and that the highway shoulders are sufficiently wide as to allow vehicles room to pull off of the highway if needed.

A second common use of fill dirt is to fill in a low lying construction site to raise the level of the building foundation in order to reduce the chances of flooding.
